Definitions
- the invention relates to a bimetal saw band, in which at least the tooth tips made of wear-resistant steel and the carrier tape a comparatively tough steel.
- Saw bands including jigsaws, need high dimensional stability as well as high wear resistance and high stress due to pressure, bending and shear forces even with the not insignificant ones Temperatures have grown due to the friction between Saw band and material to be cut result. This applies in particular to saw bands, that rotate at high speed and one when deflected by 180 ° subject to strong bending.
- Bimetallic bandsaw blades Because it is difficult to combine the required properties in one Bimetallic bandsaw blades usually exist today to combine material from a relatively tough carrier tape with high flexural fatigue strength and also a band-shaped cutting part from one High-speed steel with lower toughness but high wear resistance.
- the cutting band is so wide that at least the tooth tips result from it of the saw band or blade or the cutting teeth as a whole let work out.
- EP 0 569 346 A1 has already disclosed a bimetallic band or blade from a steel carrier tape with 0.20 to 0.40% carbon, 2.5 to 5.0% Chromium, 2.0 to 3.0% molybdenum, 0.03 to 0.04% vanadium and as a grain refiner a total of less than 0.01% niobium and titanium on the one hand and one High-speed steel cutting tape with 0.65 to 1.8% carbon, 3.0 to 6.0% chromium, 4.0 to 12.0% molybdenum and 0.5 to 5.0% vanadium known.
- a special feature of this saw band is from the point of view sufficient fatigue strength or fatigue strength the simultaneous presence of chromium, vanadium and molybdenum in both materials as well as the limitation of the total content Niobium and titanium in the carrier tape to a maximum of 0.01%.
- Both materials of the saw band also contain aluminum, up to 2.0% in the cutting part and up to 0.15% in the carrier tape.
- Japanese laid-open specification 63-007 351 describes a Bimetal saw band with high toughness and fatigue strength from a low alloy steel with 0.25 to 0.50% carbon, under 1.5% nickel, 2.00 up to 6.00% chromium, 0.20 to 1.00% vanadium, 0.20 to 1.00% molybdenum and / or below 1.50% tungsten, below 0.30% silicon, below 0.50% manganese, below 0.015% phosphorus and below 0.005% sulfur at a total of 0.20 to 1.00% molybdenum and half the tungsten content, under 0.0015% oxygen, 0.02 to 0.20% niobium and / or 0.02 to 0.20% titanium and a cutting part from a high speed steel.
- a carrier steel strip is from US Pat. No. 4,058,650 0.20 to 0.33% carbon, up to 1.5% silicon, up to 1.5% manganese, 3.5 to 6.5% chromium, 0.05 to 0.40% vanadium, 0.05 to 0.10% aluminum, 0.02 to 0.30% niobium, 1.0 to 3.0% molybdenum and / or to 4.0% tungsten and one Total molybdenum content and half the tungsten content from 1.0 to 3.0% known to improve the fatigue strength and toughness of the Basic structure can still contain up to 1.4% cobalt and up to 1.5% nickel.
- This carrier tape material is said to have low decarburization and Mark structural stability when welding with the cutting part and neither lose its toughness when the cutting part is heat treated even when tempering at higher temperatures with regard to fatigue strength ensure a hardness of approximately HRC 50.
- the cutting performance is not only dependent on the band speed (Circulation speed) depends, but also on the Feed speed of the saw band towards the material to be cut, i.e. of the contact pressure.
- the band speed i.e. of the contact pressure.
- heat development limits the possible increase in the cutting speed with regard to the limited heat resistance of the cutting teeth, so that the belt speed cannot be increased arbitrarily.
- the cutting performance can be improved with a higher feed rate or cutting pressure, because then the saw teeth deeper into the penetrate the material to be cut, then the material created during cutting Frictional heat better distributed and in the material to be cut is derived.
- To ensure a smooth or straight saw cut is also a higher one corresponding to the increased feed Blade tension required, which is only possible if the carrier tape material has sufficient flexural fatigue strength.
- An increase in the saw band feed or the contact pressure can be increased with the help of pressure rollers acting on the back of the belt.
- Pressure rollers usually consist of hard metal and lead in the approximately linear contact area with the band back to a special dynamic loading of the carrier tape material, which is supported by an elastic, but also partly linked to plastic deformation of the band back is.
- the deformation follows due to the high belt speed and the linear contact between the pressure roller and the back of the belt always a quick and complete relief.
- the band back is subject hence a strong cyclical load with a high frequency.
- the invention aims to follow from the use of a pressure roller Avoid disadvantages.
- the invention proposes a special carrier tape material in the form of a steel with 0.25 to 0.35% carbon, 0.3 to 0.5% silicon, 0.8 to 1.5% manganese, 1.0 to 2.0% molybdenum, 1.5 to 3.5% Chromium, 0.5 to 1.5% nickel, 0.5 to 2.5% tungsten, 0.15 to 0.30% vanadium, 0.05 to 0.10% niobium, 0.05 to 1.0% copper, up to 0.2% aluminum and bis 1% cobalt, remainder iron including impurities due to melting in front.
- This steel is particularly suitable as a carrier material in connection with cutting teeth made of high-speed steel with 1.0 to 2.0% carbon, 3 to 6% chromium, 1 to 5% vanadium, 3 to 10% molybdenum, 4 to 10% tungsten, 4 to 10% cobalt, up to 1% silicon, up to 1% manganese, up to 0.5% niobium and up to 0.5% nitrogen, balance iron including melting-related Impurities.
- the carrier tape preferably consists of a steel with 0.25 to 0.35% carbon, 0.3 to 0.5% silicon, 0.8 to 1.5% manganese, 1.2 to 1.8% molybdenum, 1.5 to 2.5% chromium, 0.5 to 1.5% nickel, 1.2 to 1.8% Tungsten, 0.1 to 0.8% copper, 0.15 to 0.30% vanadium and 0.05 to 0.10% Niobium, remainder including smelting impurities iron.
- the saw band according to the invention is characterized by a high flexural fatigue strength and at the same time through a high structural stability with dynamic Pressure load and favorable welding behavior when connecting of the carrier tape with the cutting part, for example by laser or Electron beam welding without filler material.
- the cheap Welding behavior is shown by the fact that there are none in the area of the melting zone Hairline cracks occur and the hardness in the area of the weld or in the Heat affected zone is uniform with a small fluctuation range.
- the risk of friction martensite developing is special low if the ratio of the contents of tungsten and molybdenum is 0.6 is up to 1.5 or 0.8 to 1.4 and is preferably 1.
- the presence of copper also has a positive effect on the formation from friction martensite and cracks as well as crack growth because Copper the structural stability even at high cooling rates improved. This applies not only to the area of the pressure rollers Strap back, but in the same way for the weld between carrier tape and cutting part. Eventually the copper replaced in the carrier tape material according to the invention also otherwise in Aluminum necessary for the toughness and strength of the welding zone in the carrier tape.
- Table I below shows two carrier tape materials TB1 and TB2 according to the invention and two conventional carrier tape materials TB3 and TB4 and four sawtooth materials Z1 to Z4 made of high-speed steel.
- Table II below shows the material combinations for five bandsaw blades S1 to S5, of which samples were examined with regard to their structural stability and flexural fatigue strength.
- the sample 5 is against each in a manner not shown in the drawing Movement in relation to the pendulum table 2 secured.
- Sheet metal strips of the dimension were used to determine the fatigue strength 8 x 1.35 x 80 mm and 20 x 1.5 x 80 mm at one temperature from 1180 ° C under protective gas, annealed and quenched as well as then tempered three times at 560 ° C.
- the main components of the spring rocker are a swing beam, who is held in a fixed camp at one end and at the other end by an adjustable double eccentric is driven, and two via handwheels parallel height-adjustable crossbeams (base plates) of an upper one and a lower test floor.
- the lifting height of the eccentric can be adjusted in steps of 1.5 mm, set between 0 and 36 mm, the stroke amplitude is linear from 0 (fixed bearing) to the maximum value at the eccentric.
- On the lower one and the upper test floor each have up to six sample shots with 16 sample places next to each other.
- test specimens are loosely inserted into the receptacles at both ends and form free-standing flexible beams of free length L on two bearing points
- the force distribution to generate a corresponding bending moment was done by a central deflection, for which purpose over each individual sample a contact piece made of hard metal and positioned exactly in the middle was.
- test stress was calculated according to a known formula from the measured deflection and the band dimensions for an elastic modulus of 206,000 N / mm 2 .
- FIG. 3 shows the number of the respective load changes in dependence on the ratio of the contents of tungsten and molybdenum in the area from about 0.6 to about 1.5 again. A maximum is clearly shown a ratio of 1.0.
- the service life of a conventional saw band S1 (standard sample) was set at 100% with an initial cutting performance of 20 cm 2 / min and the service life of the saw band S2 according to the invention was 280%.
- the contact pressure of the saw band was increased to such an extent that an initial cutting performance of 35 cm 2 / min resulted.
- the tool life in this test was 230%.
- Further tests with the saw bands S3 resulted in a service life of 340% with an initial cutting performance of 35 cm 2 / min and a service life of 345% with the saw band S4, while the saw band S5 according to the invention achieved a service life of 295 at an initial speed of 35 cm 2 / min % reached.
- the service life of the conventional saw band S1 was only 58% with the aforementioned initial cutting performance. This is due to the occurrence of friction martensite and the resulting fatigue fractures in the back of the belt.
